 When running `vue-cli-service`, environment variables are loaded from all [corresponding files](#environment-variables). If they don't contain a `NODE_ENV` variable, it will be set accordingly. For example, `NODE_ENV` will be set to `"production"` in production mode, `"test"` in test mode, and defaults to `"development"` otherwise.
 
-Then `NODE_ENV` will determine the primary mode your app is runnning in - development, production or test - and consequently, what kind of webpack config will be created.

 With `NODE_ENV` set to "test" for example, Vue CLI creates a webpack config that is intended to be used and optimized for unit tests. It doesn't process images and other assets that are unnecessary for unit tests.
